Spoilt baby

My baby is 6 months old ; and like I need to get back to work pretty soon but she literally won’t sit with anybody. I went to the dollar store earlier and it’s like 5 min away from my house and i left her with my sister and when I came back I can hear her all the way outside screaming !!!! Turning red and everything but as soon so I picked her up she started smiling, and calmed all the way down . How do I get her out of doing that . People saying I spoiled her to much and she will never let anybody babysit her , I can’t clean the house or nothing , is there anything I can do to make her not so attached
